ln the perferred form of the inyention ves illustrated in the drawings I ut111ze a pen' of vertically disposed pipes or pump casings 1 and 2 that are reciprocnble andconnected to move in opposite directions. '.lfhese cesin s are suspended over an equahzlng wheel 3 oceted intermediate of 'the casings and provided with suite-ble beermgsin the beering base el of the pump, by means of i suspending chain 5, which et its ends 1s ettached to collars 5' on the'respective cesings. The cnsin are thus suspended with their lower ends m the well 6 and are adepted to reciprocate vertically through openings in the top Well T of the well as .seen m Figure l.

The' vzrlve rods( are actuated on their' working ,strokes n1-id lifted vertically, through thednstrnmentnlity of e combined sivspen'dingz land actuating wheeler sprocket t2-und the iienihleconnection or sprocket' chain 13e passed'- over andls'uspendcd' on the wheel as eeen in Figure' V1. The `Wheeli is osts 14 risingt from the base 4,-j sindl the" o'scillutnhl'eI lshaft-11% of the wheel is jonrnwled in the posts to'oscillnte and thus nctnate `the pis-` ton-rods'. The movement o'li therods is si# lnuitnneous, but one rod is actuated onits working' stroke wliile'-tl1e other rod' is moving on its return stroke to operate. the pistons and valves in the respective cylinders 9 nd 10, for the purpose of elevating the By suit- `able connections from a source. of power to the oscillatable crm 16 aiiixed to the shaft 15, the latter may be actuated to oscillate the Wheel'l2, and e balance wheel 17 is providedon the shaft to stabilize the movement. In this manner it will be apparent `thet the notion ofthe sprocket wheel 12 and its chain 13 causes alternating lifting strokes of the pumpA rods 11 whereby the colnmns'of water in the two casings ure elevated, and the water eventually emerges from the upper open ends of the oesings The water is drawn in through the lower, open valve controlled ends of the cylinders 9 and 10 in usual or suitable manner.

In addition to the lifting action ol' the pump rods and their pistons in the cylinders 9 und 10,' the columns of water are given un auxiliary lift by bodily moving the suspended cnsings l und 2. ,-Thesc ccsings are recprocated in synchronsm with the move ments of the pump rods, euch casing being piene' due to t vpump rods.
